Function Smooth Streaming Smooth streaming offers solutions to improve the video quality in different network conditions. For example, in poor network conditions, adapting to the detected real-time network condition, streaming bit rate and resolution are automatically adjusted to avoid mosaic and lower latency in live view; in multiplayer network conditions, the camera transmits the redundant data for the self-error correcting in back-end device, so that to solve the mosaic problem because of the packet loss and error rate. Metadata Metadata uses individual instances of application data or the data content. Metadata can be used for third-party application development. Power Protection The camera supports a wide voltage range of 10 VDC to 48 VDC. If the voltage instability occurs, the camera still works properly. The camera supports reverse polarity protection which can avoid the camera malfunction caused by false operation. Anti-Reflection Bubble This anti-reflection bubble design avoids the IR reflection of the raindrop and dust on the bubble and improves the image quality.
